will fit my F10 without the need for spacers etc. The tyres are 245/40/18 instead of the recommended 245/45/18 but I don't think that would matter much, or would it?

Thanks.

I can't identify what style they are, look like replica rims, but not sure, so will pass on opinion. But if they are similar to Styling 135, 8x18" with ET 20, will be pushed out 10mm without need for spacers.

Tyre size is wrong, too low a profile for the F10. You do need the 45 aspect ratio to get the sidewall dimension correct, particularly as you are after better ride quality.

Thank you for that. I looked at the link you very kindly sent and I see they are style 166. I wasn't sure about them.. I could buy them and fit new tyres of the correct size. How do you think they would look on the F10?

Styling 166 is a 19" rim, plus it is 8.5" width with ET 12. They would be about 25mm out into the arches, if they do fit.

I don't want to go bigger than 18'' for ride quality purposes. What do you reckon about these?

You would need to know the exact size and offset, plus I'd be concerned of the quality of the rims themselves. There are good and bad in replica rims. I personally would prefer a rim type from the OEM range for the car, but obviously will cost more if you can find a used set.

It is a difficult shout, as to what solution is going to give you what you want. Will an 18" non run-flat improve the ride quality enough over rough roads? Rim weight and tyre specification could be as critical as size and a move to a non run-flat.

Plus the comment in the other thread, "it's smoother, but not £1200 worth smoother".

I know, it's a difficult call. Maybe I should keep the current rims and just replace the tyres. But the OEM 17'' rims aren't great looking by any means.

Sorry to barge in on the thread but i just joined the forum and I do not yet have the priviledge to create a new thread.
Does anyone know why BMW does not include the 245/50 R17 tyre size as an option for the F10?
I have a 528 with 18" rims and 245/45 tyres. I wish to change down to 17" due to suffering a lot of tyre damage caused by bad road conditions were i live.
The 17" rims would allow a higher profile tyre and hence better cushioning effect.
BMW lists the 225/55 R17 as the only option.
I do not want to loose the traction quality of the 245s but nobody at the local BMW dealership can inform me why the 245/50 R17 is not listed.
